Top Forums Programming Odd behavior from GDB while trying to cross-debug an embedded Linux application. Post 303031547 by Circuits on Friday 1st of March 2019 04:54:42 PM

Unfortunately I got pulled off into a bug and had to put this aside for a few days but now I have some more time.



@Corona688


Just to be sure I remounted a brand new copy of the rootfs from a branch and then downloaded the Codebase for that branch and repeated the above exercise and got the same behavior. Another thing I find odd, in the debugger console at the end of the output I showed above it says:


Code:
A problem internal to GDB has been detected,
further debugging may prove unreliable.
 Quit this debugging session? (y or n)

but it's actually frozen. Entering y or n does nothing. So I have to manual terminate the debugging session.




I tried running gdb-multiarch from a terminal instead of using it through Eclipse and ended up with similar output except right at the end it says:

Code:
Segmentation fault (core dumped)

So, this doesn't seem to be an Eclipse problem. Maybe it is a gdb-multiarch problem?


EDIT: I take that back the output is jumping all over I tried again running gdb-multiarch with sudo and ended up with the same output as before, no mention of a seg fault.
